不解体检测柴油机内部异常状态,这是最理想的检测方法。为此,日本铁路综合技术研究所等单位于今年2月中旬召开了技术研讨会,确定把根据排气分析进行柴油机内部诊断作为研究课题。决定采用气体色谱分析法对柴油机的排气进行化学分析。石油是由150种以上碳氢化合物组成的复杂物质,且因原油产地 Do not disintegrate to detect abnormal internal diesel engine, which is the best detection method. To this end, Japan Railway Comprehensive Technology Research Institute and other units held a technical seminar in mid-February this year, to determine the basis of exhaust analysis of diesel internal diagnosis as a research topic. Decided to use gas chromatographic analysis of diesel exhaust gas chemical analysis. Oil is a complex substance composed of more than 150 hydrocarbons, and because of crude oil origin
